**Abstract:** This package contains data and
three computer codes to calculate:

- neutron energies,
differential cross-sections and differential yields;

- thick-target yields and white
neutron spectra from two-body neutron producing reactions;

- differential cross
sections and energies of (n,p), (n,d), (n,t) and (n,4He) reactions which are
time-reversed neutron production reactions (using detailed balance
calculations)

The package is can be
downloaded from http://www-nds.iaea.org . or as iaea-nds-0087ver12.01.zip from here.

**Description
of the 3 codes: **

*1) NEUYIE:* Accelerator-based mononenergetic
neutron production This program calculates neutron energies, differential
cross-sections and (for isotopic pure targets) differential neutron yields for
monoenergetic neutron sources using internal tables. The Legendre coefficients
of the differential cross sections are stored in the files *.KOE, the energy
loss tables needed for the neutron yield calculations in the files *.ELS. The
neutron yields are given for an energy loss of the projectile that results in
10 keV neutron energy spread at 0 degree.

*2) WHIYIE:* White neutron yields from two-body
reactions This program calculates angular differential thick-target neutron
yields of white neutron sources that are based on the two-body reactions
covered under 1). As an option, a white spectrum at a chosen angle ready for
plotting is produced.

*3) TIMREV:* Differential cross sections and
energies of (n,p), (n,d), (n,t) and (n,alpha) reactions This program calculates
differential cross sections and energies of some (n,p), (n,d), (n,t) and
(n,alpha) reactions by detailed balance from the time reversed reactions
covered under 1).
